Well, I was in a local pet store inspecting the cage of a Florida Slender Brown Scorpion (Centruroides gracilis), picked up the bark and bang... stinger into the thumb. Never had one be so ready and so defensive before, but I feel like a dip#$%^$%^$%^$%^& nonetheless so figured now that I have a decent pic, I'd post and humble myself.
Their venom is neurotoxic, causes the brain to misfire neurotransmitters, the end result is paralysis. I lost all sensation in the tip of my thumb for about 8 hours. Felt just like it does when you burn the tip of a finger and you have little or no sensation in it for a few days? No signs of anaphylaxis, thankfully.
Anyway... she came home with me. A constant reminder of my first real envenomation.
